The outcome

What happened to each lost opportunity.

The part

What it is

Lost to a named competitor, lost to inaction, or disqualified. The three have entirely different implications and are usually recorded as one.

Disqualified deals are not losses and including them distorts every ratio built from the data.

The smallest level

The attributes it carries

Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
